A big problem of the American two-party system is that you can't distinguish a vote against one party from a vote for the other party: Did all of that 49.8% vote for Trump, or was he the "lesser of two evil" for a lot of people who genuinely hated Harris?

Voting is always a compromise. No candidate ever perfectly represents one's own views on every issue. So IMO reasons for voting "for" a candidate or "against" another don't really matter.
